Senatorial Yamabuki

#a62905
Notes

Senatorial Yamabuki (#A62905) is a deep red with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (13°, 94%, 34%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Senatorial
adjective

Latin senātōrius, of the senator — adjectival suffix. As a color modifier, senatorial implies a saturated-and-aristocratic-and-Roman-Republic quality, the deep-rich color of Roman-Senate toga praetexta purple-bordered ceremonial-citizen-class livery. Sits at the bold-and-aristocratic end of the grid, parallel to patrician and imperial.

Yamabuki
noun

Kerria japonica, the Japanese rose-family shrub whose bright yellow-orange flowers cover steep hillsides in late spring. Yamabuki-iro (mountain-rose color) gave Japanese its name for a saturated yellow-orange hue used in court robes and woodblock prints. The color refers to a fully open kerria flower: a saturated, slightly red-shifted yellow-orange with the satin finish of small five-petaled bloom. Warmer than canary, lighter than marigold.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
